3M 7100133704 Scotch-brite Exl Pro Unitized Wheel 3 Inch Ao

Product Description

The 3M 7100133704 Scotch-Brite EXL PRO EX-UW Unitized Abrasive Wheel is a nonwoven abrasive wheel built for laser braze finishing on silicon bronze. Its open-web, layered construction resists heat buildup and loading, which extends service life and reduces the need for additional surface preparation between passes. The wheel delivers a clean, smooth edge without smearing — a critical requirement when working with heat-sensitive base materials. Weighing 1.574 pounds, this wheel measures 3 inches in diameter and is designed for consistent, repeatable surface finishing results.

This wheel is used in metalworking and fabrication environments where silicon bronze laser brazing is performed. It is suited for blending and finishing passes on brazed joints in automotive, manufacturing, and precision fabrication applications. The unitized construction allows operation in both clockwise and counterclockwise directions, giving technicians flexibility in tool mounting and pass direction without compromising wheel integrity or finish quality.

Key Features

• Nonwoven open-web construction resists loading and extends effective service life
• Minimizes heat buildup to protect heat-sensitive base materials during finishing
• Resists smearing for cleaner surfaces and reduced prep time
• Layered unitized construction operates in clockwise or counterclockwise direction
• Designed specifically for blending and finishing silicon bronze laser braze joints

Compatibility

Designed for laser braze finishing applications on silicon bronze; suited for use with compatible rotary finishing tools and right-angle grinders that accept 3-inch diameter unitized wheels.

Installation Notes

Installation should be performed by a qualified metalworking technician. Confirm that the tool's rated RPM meets or exceeds the wheel's maximum RPM rating before mounting. Power down and isolate the tool before changing wheels. Inspect the wheel for damage before each use and do not use a wheel that shows signs of cracking, gouging, or delamination.
